+Subject: [PATCH] is_ntfs_dotgit: use a size_t for traversing string
+
+We walk through the "name" string using an int, which can
+wrap to a negative value and cause us to read random memory
+before our array (e.g., by creating a tree with a name >2GB,
+since "int" is still 32 bits even on most 64-bit platforms).
+Worse, this is easy to trigger during the fsck_tree() check,
+which is supposed to be protecting us from malicious
+garbage.
+
+Note one bit of trickiness in the existing code: we
+sometimes assign -1 to "len" at the end of the loop, and
+then rely on the "len++" in the for-loop's increment to take
+it back to 0. This is still legal with a size_t, since
+assigning -1 will turn into SIZE_MAX, which then wraps
+around to 0 on increment.
